Dear Doctor: What can you tell me about lupus? Is it true that there are two different kinds? One of the skin, and one that affects the entire body?

Dear Reader: There are actually several types of lupus-related skin conditions. While some of these can affect the skin alone, many are related to systemic lupus erythematosus (SLE). This is the most common type of lupus and can affect the skin and any organ in the body. First recognized in the 19th century, SLE was initially thought to be a skin disorder because of its obvious external effects. It took many more years for physicians to realize that it was actually a systemic autoimmune disease with the ability to affect any organ in the body.

In the United States, estimated prevalence of the disease varies, but is generally regarded as slightly more than 1 in 1,000 people. In adults, lupus occurs more frequently in women than in men, with a female-to-male ratio of about 8-to-1. In the United States, it's more common among people of African, Asian and Hispanic ancestry, with African-Americans having nearly 2 1/2 times the likelihood of lupus compared to those of European ancestry.

Genetics are a significant risk factor for the disease. In a study among Latinos, if one sibling had SLE, the other sibling had a 29 times greater risk of developing lupus compared to the rest of the population. Certain medications also can increase the risk of lupus.

Lupus develops when the immune system's antibodies attack cell structures -- the nuclei and membranes -- and form immune complexes that circulate and deposit in different portions of the body. These immune complexes, made of antibodies attached to antigens, bring in white blood cells that release inflammatory chemicals, which damage the tissues further.

The disease is marked by cycles of flares and remissions. When the disease is flaring, or active, a person suffers from fatigue, muscle aches, joint pain and sometimes fever. He or she also may lose a considerable amount of weight.

Lupus affects the kidneys 50 percent of the time, which can lead to kidney dysfunction, and the gastrointestinal system 40 percent of the time, which can include the esophagus, the small or large intestine, the pancreas and the liver. Joint pain and arthritis are also common, and although lupus can affect any joint, the knees, wrists and fingers are most susceptible.

Lupus can also damage the heart and lungs, and the deposits of immune complexes can cause inflammation of blood vessels. In short, any part of the body can be affected, including the brain, eyes, blood cells, muscles, bone and skin.

People with systemic lupus most typically develop a type of rash that affects the face at the cheeks and nose, described as a "butterfly" rash. The rash is often exacerbated by sun exposure, and this may be the first sign of lupus, occurring months or years before other symptoms.

Some types of lupus-related skin conditions are not associated with systemic lupus. These lesions, commonly diagnosed with a biopsy, are often circular and plaquelike and can be located anywhere upon the body.

Treatment for these skin conditions includes non-steroidal immune-modulating creams and possibly immunosuppressant oral drugs; stronger immunosuppressant drugs are necessary for systemic lupus erythematosus.

With all types of lupus, treatment is focused on controlling symptoms. With SLE specifically, it will be a lifelong commitment.

Patients Should Be Told of the Risks Associated With Apitherapy

Ask the Doctors by by Eve Glazier, M.D. and Elizabeth Ko, M.D

Dear Doctor: What on earth is bee-sting therapy -- and what is it supposed to do? I ask because apparently someone died after having it.

Dear Reader: Using bee products like honey, pollen, royal jelly and venom to treat illness and promote healing is a practice known as apitherapy. The word comes from apis, which is the genus the honeybee belongs to. References to apitherapy date back to ancient Egypt, Greece and China. Hippocrates is said to have used bee venom to ease the pain of arthritis, which is one of the primary targets of modern-day treatment. The theory is that the bee sting causes the immune system to mount an anti-inflammatory response that is beneficial to the patient. However, that same immune response can become deadly.

That's the case with a woman in Spain who had been undergoing monthly treatments in which she was stung by live bees to address muscle issues and stress. She had no adverse reactions for two years, but in that final session she developed "wheezing, dyspnea, and sudden loss of consciousness immediately after a live bee sting," according the Journal of Investigational Allergology and Clinical Immunology. Although the private clinic treated her with corticosteroids, which counter inflammation, they didn't have any epinephrine, which is used to reverse extremely low blood pressure, wheezing, hives and other symptoms of a severe allergic reaction. An ambulance reportedly took 30 minutes to arrive, and despite medical treatment at a hospital, the woman later died.

The report about the incident, which took place in 2015, was published earlier this year. But because bee sting therapy currently has a few high-profile celebrity proponents, the story has received quite a bit of attention. According to the analysis of the case, this was the first reported death due to bee venom therapy. The authors point out that although a patient may initially tolerate the venom, a hypersensitivity reaction is still possible. In fact, repeated exposure can lead to a higher risk of sensitization.

Bee venom, also known as apitoxin, is a complex mix of proteins, peptides and bioactive agents. The main ingredient is melittin, a small protein that disrupts the membranes of red blood vessels at the site of the sting, causing them to burst. Blood vessels expand in the presence of melittin, which can cause a swift drop in blood pressure. Add the presence of a second protein that causes burning pain, and histamines for itching and swelling, and a drop of bee venom delivers a world of hurt.

But it's that complex chemistry of the venom that has captured the imagination of healers for millennia. Melittin turns out to be a powerful anti-inflammatory agent. Injections of bee venom have been used successfully to fight inflammation in patients with arthritis and multiple sclerosis. In recent research, certain cancers appear to slow their rate of growth in the presence of melittin.

Still, despite its potential medicinal uses, bee venom is a toxin. Patients should be informed of potential adverse reactions. Practitioners of venom therapy must be able to identify patients who have developed sensitivity, must be properly trained in managing severe reactions and must have rapid access to emergency care.

Cause of Vestibular Migraines Not Known

Ask the Doctors by by Eve Glazier, M.D. and Elizabeth Ko, M.D

Dear Doctor: I have just been diagnosed with vestibular migraines. Could you give me information on the symptoms and treatment?

Dear Reader: Vestibular migraine is a relatively new diagnosis used by doctors to describe the association between vertigo and migraines. The connection itself, however, has been recognized by doctors since 1873, with the condition given multiple names, including vertiginous migraines, migrainous vertigo and migrainous vestibulopathy.

No defining test is used to diagnose the condition; instead, diagnosis is based on a person's recurrent symptoms.

The first criterion is a present or past history of migraine headaches. Second is recurring vertigo. These can be episodes in which the room seems to be spinning or in which a stationary person has feelings of movement. In vestibular migraines, the vertigo can last from five minutes up to 72 hours.

The third criterion is that more than half of these vertigo episodes occur with at least one symptom of a migraine. That symptom could be a headache that is one-sided, severe and worsened by physical activity; visual flashing wavy lines noted by many migraine sufferers; or extreme sensitivity to light and sound. Severe sensitivity to sound is especially common in vestibular migraines.

The fourth criterion is that the condition not be caused by another condition.

Based on these criteria, doctors are diagnosing more people with vestibular migraines. A population-based study found that 1 percent of Germans had vestibular migraines at some point in their lives. Other research has established that the condition occurs more often in women than in men and is diagnosed more often in children than adults. In adults, the average age of diagnosis is about 40 years of age.

The cause, however, is not known. Vertigo could act as a migraine trigger; or a neurologic or inner ear problem could cause both vertigo and migraine.

Treatments for an acute attack of a vestibular migraine include the typical medications used for migraines. Drugs known as triptans, such as Imitrex, Relpax, Zomig, Maxalt and Amerge, can be used for migraine symptoms and may ease the vertigo as well. But some doctors specifically treat the vertigo using antihistamines such as meclizine or dimenhydrinate or with benzodiazepines such as clonazepam or lorazepam.

To prevent a vestibular migraine, try to avoid those factors that increase your risk of a migraine. Because many migraines are caused by stress, limiting the amount of stress or finding ways of managing stress is a good starting point. Getting enough sleep is helpful, as is limiting caffeine and alcohol, eating regular meals, staying away from food additives and avoiding dehydration. Medications to prevent vestibular migraines include calcium channel blockers, such as verapamil; beta-blockers; tricyclic antidepressants at low doses; and the antihistamine betahistine. Physical therapy to improve balance and decrease the sensation of vertigo may also prove beneficial.

As I've learned from my own patients, symptoms of vestibular migraine can be debilitating. But there is hope: Start by avoiding migraine triggers, taking preventive medications and getting physical therapy. Those three actions should, I hope, decrease your attacks.
